TL;DR: The numbers of new cancer cases in 16 common sites occurring in 1980 have been estimated and it is suggested that, with declining incidence rates for stomach cancer and the continuing rise for lung cancer, the latter would become the most common cancer in the world by the end of 1981.
Abstract: The numbers of new cancer cases in 16 common sites occurring in 1980 have been estimated for 24 areas of the world for which the United Nations produces population estimates. For the world as a whole, the total number of new cases was 6.35 million, almost exactly evenly divided between the developed and developing countries. In males, the most important sites were lung, stomach, colon/rectum, mouth/pharynx, prostate and oesophagus, and in females breast, cervix, colon/rectum, stomach, corpus uteri and lung. When the two sexes are combined, stomach cancer emerges as the most common cancer in 1980 (669,400 new cases per year), but this estimate is only slightly greater than that of lung cancer (660,500 new cases), and comparisons with earlier estimates for 1975 suggest that, with declining incidence rates for stomach cancer and the continuing rise for lung cancer, the latter would become the most common cancer in the world by the end of 1981. The implications for cancer control in the developed and developing countries of the world are discussed.

TL;DR: Variations in the risk of those tumours between different countries and different ethnic groups provide important information on the relative importance of environmental and genetic factors in their aetiology.
Abstract: The International Agency for Research on Cancer has coordinated a worldwide study of the incidence of cancer in childhood. Contributors from over 50 countries have provided data. This paper presents a summary of some of the major results. The incidence rates and relative frequencies of childhood cancers are described according to 12 diagnostic groups, defined mainly in terms of tumour morphology. Variations in the risk of those tumours between different countries and different ethnic groups provide important information on the relative importance of environmental and genetic factors in their aetiology.

TL;DR: Stomach cancer is the most frequent neoplasm in Costa Rica; although rates are declining, they are second only to those observed in Japan; there are marked variations in risk by region, suggesting important environmental influences in etiology.
